So 161 divide 7 equals 23 so therefor he types 23 words per minutes. 23 times 20 equals 460. I think he can type 460 words in 20 minutes.

deff fn [24]

Answer:

a)0.2240

b)0.5768

Step-by-step explanation:

Given:

µ=3

Poison probability is given by :

f_k=\frac{\mu^ke^-^\mu}{k!}

a) Evaluating at k=3

f(3)=\frac{3^3e^-^3}{3!} \approx 0.2240

b)Evaluating at k=0,1,2:

f(0)=\frac{3^0e^-^3}{0!} \approx 0.0498

f(1)=\frac{3^1e^-^3}{1!} \approx 0.1494

f(2)=\frac{3^2e^-^3}{2!} \approx 0.2240

Use complement rule:

P(x≥3)= 1 - f(0) - f(1) - f(2)= 1- 0.0498 - 0.1494 - 0.2240 =0.5768
